6 One of the specimens (the type) is not sexed, but being larger than the other is 

 probably a male. ■

''Two specimens. 



«No. 142878, U. S. Nat. Mus. (Biological Survey Coll.), Motzorongo, Vera Cruz, 

 March 5, 1894; Nelson and Goldman. This specimen is doubtfully determined by 

 the collectors as male; but being so much smaller than the other, except in length of 

 tarsus, there is reason to justify the suspicion that it may be a female.
